OceanStor 9000 network architecture
The OceanStor 9000 network consists of the following: - A front-end service network that connects OceanStor 9000 to the customer's network - A back-end storage network that interconnects OceanStor 9000 nodes - A management network that connects OceanStor 9000 to the customer's maintenance network OceanStor 9000 supports multiple networking modes, including 10GE, InfiniBand, and GE networking to meet different network requirements.

Quota tree function of V3 series unified storage
A quota tree is the root directory of a file system. Quota trees are special directories. The following distinguishes a quota tree from a common directory: 1. Quota trees can only be created, deleted, or renamed by administrators using the command-line interface (CLI) or graphical user interface (GUI). Only empty quota trees can be deleted. 2. Quota trees can be shared using protocols and cannot be renamed or deleted during sharing. 3. Administrators can manage quotas such as file quantity or capacity under the quota tree.

IP failover policy of V3 series unified storage
During the system initialization, the system automatically adds all Ethernet ports and bond ports of clusters to the default failover group. An IP address fails over first to the port at the same position in the peer controller, then to ports at other positions in the peer controller, and last to ports in the local controller. It can float between various interface modules. Which port it floats to is related with the port location, not the port rate. Later versions will allow you to customize failover groups.

Method used to bond ports on OceanStor V3 unified storage systems
On OceanStor V300R001 storage systems, you can bond multiple iSCSI host ports. In doing so, the data transmission rate of these iSCSI host ports can be improved significantly (assuming other components do not reach their performance bottlenecks). For details, see Bonding Ethernet Ports .
